APPARATUS FOR CHARGING FURNACES OR OVENS.

Application filed February 9, 1912.

i To all whom it may concern:

Be it known that I, UTLEY VVnoou, a citizen of the United States,residing in Ardmore, Pennsylvania, have invented certain Improvements inApparatus for Charging Furnaces or Ovens, of which the following is aspecification.

The object of my invention is to provide a simple and compact form ofportable de vice for charging kilns, ovens or furnaces (referred to inthe claim simply as a furnace an object which I attain in the man nerhereinafter set forth, reference being had to the accompanying drawing,in which- Figure 1 is a vertical sectional view of a pyrites kiln withcharging device therefor in accordance with my invention, the latterbeing shown in position for delivering a charge into the kiln; Fig. 2 isan end view of the charging device, and Figs. 3 and t are plan or topviews of the same on a reduced scale, and illustrating the manner ofintroducing the charging boxes into or withdrawing them from the kiln.

In Fig. 1 of the drawing, 1 represents the receiving chamber of apyrites kiln although the same may be the receiving chamber of any otherform of furnace or oven, 2 representing the charging opening in thefront wall of the kiln and 3 one of the swinging plates whereby saidopening can be normally closed. The charging device consists of awheeled truck 4 running on rails which are laid in front of a row ofkilns disposed end to end so that it can be traversed from kiln to kilnin order to charge the same in succession, projecting yokes 5 at eachend of the truck constituting handles whereby the truck may be readilypushed along over the rails.

Rigidly supported upon the truck is a central post 6 and free to turnupon the latter is a turntable 7, upon which are mounted the bearings 8for a series of shafts 9 dis posed side by side parallel to one another,and each carrying at one end a charging box 10, the opposite end of theshaft being squared, or otherwise formed, as at 11, for the reception ofa suitable handle whereby it may be turned in its bearings, collars 12on each shaft serving to prevent any longitudinal movement of the shaftin its bearings.

Each of the charging boxes being pro- Specification of Letters Patent.

Serial No. 676,606.

vided with its proper load the truck is run along in front of the row ofkilns with the charging buckets and their shafts 9 disposed parallelwith the track rails until the truck approaches the kiln which is to becharged, WllClOllPOll the charging boxes are swung through the chargingopening 2 of the kiln, as shown in Fig. 3, the turntable turning on itscentral post in order to permit such movement which continues until thecharging boxes are at a right angle to the track rails and are containedcompletely within the receiving chamber of the kiln, as shown in Fig. t,whereupon the shafts 9 are turned throughout a partial revolution so asto dump the contents of the boxes into the receiving chamber of thekiln, and are then turned backward again so as to restore the chargingboxes to their former position, after which the truck is moved eitherforward or backward upon the rails and the charging boxes are swung outof the kiln again and are conveyed by the truck to the place where theyreceive their fresh charges.

I am aware that furnace charging apparatus has before been devisedcomprising a truck movable on rails across the front of a series offurnaces disposed side by side or end to end, such truck being providedwith a transversely moving charging box carrier so that the charging boxcould be thrust directly into the furnace or withdrawn directlytherefrom and could be turned when in the furnace chamber so as to dumpits load.

A charging device constructed in accordance with my invention requiresfor its operation considerably less space in front of the row of kilnsor ovens or furnaces than is re quired by such previous charging devicesand the introduction of the charging boxes into and the withdrawal ofthe same from the receiving chamber is effected without the use of theelaborate projecting and retracting mechanism heretofore required, suchoperations in my improved charging device simply necessitating thepartial turning of the turntable on its pivotal axis, in order to permitthe charging boxes to swing into and out of the receiving chamber.

In the drawings I have shown the turntable as provided with a group ofthree charging boxes and their appropriate shafts, but less than thisnumber may be used if desired, or more, depending upon the ca pacity ofthe charging opening 2 for the insertion and Withdrawal of the chargingboxes in the manner described.

I claim:

A furnace charging device consisting of a truck having thereon a pivotedturntable with bearings, longitudinally fixed shafts of one or morecharging boxes mounted in said bearings, said shafts and their boxesbeing of such length as to reach fully into the furnace When the truckis in mid position, and

the boxes being adapted to swing into or out of the furnace as the truckapproaches or recedes from said mid position.

In testimony whereof, I have signed my 15 name to this specification, inthe presence of two subscribing Witnesses.
